CONSTITUTION:Control mode selecting means 3 initially selects an ordinary power control mode, and controls energization control means 2 by the ordinary power control means at the initial time of starting. If power interruption time detecting means 5 detects power interruption for a predetermined time or more, it judges that a power source of a heat generator 1 is special power, and the means 5 outputs a control mode alter command. The means 3 which receives the command alters the ordinary power control mode to a special power control mode. When reset command generating means 6 outputs a reset command in a time zone out of special power energizing time zone, the means 3 alters the control mode to the ordinary power control mode.</p> |
